There’s automotive plugs which use more or less standard spade connectors which you can wire yourself and they can easily achieve 10A and things like relay sockets can manage 40A or more. JAE is one of the brands manufacturing all kinds of connectors, with and without panel connectors, but there’s a ton of manufacturers around. I suppose on marine stuff you can find connectors like that too.

But if it’s for a LED strip and you don’t need to constantly move them around, I’d suggest using a dirt cheap spade connectors with color coding (reverse male/female connectors on the live one so it’s physically impossible to connect led strip in reverse polarity). Or even cheaper, use screw terminals and be extra careful when wiring the strip in.

And for the dupont-style connector commonly seen on LED strips, 10A feels like quite optimistic value. Obviously a LED strip can pull 10A and many times that, but quickly googled ballpark estimation for 2,5m 10A led strip calls for 2,5mm² wiring all the way trough and your cheap flexible LED PCB from amazon/ebay is pretty far from that. But that depends heavily on what you actually have and if you’ve measured 6A then it’s pretty reasonable to have the rest of the setup to manage 10A.
